(gray marked fuses are optional)
The fuses on this mainboard can be used several times (polyfuses). Shortly after the error state has been eliminated, the fuses reset to the original state.
Mainboard current requirement
You require a Pentium4 power supply nit as per the ATX12V specification for this mainboard. If you do not have a PC from Fujitsu Siemens Computers, make sure that the power supply unit provides the required amperages.
Resource | Voltage | Maximum | Maximum current |
